Dual,Wideband,High Output Current
Operational Amplifier with Active Off-Line Control
Check for Samples:OPA2673
FEATURES DESCRIPTION
?WIDEBAND+12V OPERATION:The OPA2673provides the high output current and 340MHz(G=+4V/V)low distortion required in emerging Power Line
Modem driver applications.Operating on a single ?UNITY-GAIN STABLE:600MHz(G=+1)
+12V supply,the OPA2673consumes a low16mA/ch ?HIGH OUTPUT CURRENT:700mA
quiescent current to deliver a very high700mA output ?OUTPUT VOLTAGE SWING:9.8V PP current.This output current supports even the most
demanding Power Line Modem requirements with ?HIGH SLEW RATE:3000V/m s
greater than460mA minimum output current(+25°C ?LOW SUPPLY CURRENT:16mA/ch
minimum value)with low harmonic distortion.?OVERTEMPERATURE PROTECTION CIRCUIT
Power control features are included to allow system ?FLEXIBLE POWER CONTROL
power consumption to be minimized.Two logic ?OUTPUT CURRENT LIMIT(±800mA)control lines allow four quiescent power settings:full
power,75%bias power in applications that are less ?ACTIVE OFF-LINE FOR TDMA
demanding,50%bias power cutback for short loops,
and offline with active offline control to present a high APPLICATIONS
impedance even with large signals present at the ?POWER LINE MODEMS
output pin.
?MATCHED I/Q CHANNEL AMPLIFIERS
Specified on±6V supplies(to support+12V ?BROADBAND VIDEO LINE DRIVERS
operation),the OPA2673also supports up to+13V ?ARB LINE DRIVERS single or±6.5V dual supplies.Video applications
?HIGH CAP LOAD DRIVERS benefit from a very high output current to drive up to
10parallel video loads(15?)with<0.1%/0.1°dG/dΦRELATED PRODUCTS nonlinearity.

SBOS382F–JUNE2008–REVISED 90af1574f46527d3240ce040 This integrated circuit can be damaged by ESD.Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure.Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
